If all constituents in an analytical suite are not detected in a deep monitoring <br />well during the first two consecutive events, that analytical suite may be removed from the <br />schedule for that well with Central Valley Water Board staff concurrence. <br />2 For nondetectable results. All concentrations between the Method Detection Limit and the <br />Practical Quantitation Limit shall be reported as trace. <br />'Maximum PQLs for bromomethane, dichlorodifluoromethane, Freon 113 and MTBE are 1 µg/l. <br />4 Maximum PQLs for Coumaphos, Demeton, and Dichlorvos are 1 µg/l, for Fensulfothion and <br />Naled are 2.5 µg/I, for Mevinphos is 3.5 µg/I, and for Azinphosmethyl is 5 µg/l. <br />5 Maximum PQLs for dichloroprop, 2,4 D and 2,4 -DB are 5.0 µg/I, Dalapon is 13 µg/I, for MCPA <br />and MCPP are 500 µg/I, and for dinoseb is 2.5 µg/I. <br />6 Maximum PQLs for Barban, Chlorpropham, Mexacarbate, Propachlor and Propham are 5 µg/I. <br />
